Abstract
Description
Technical Field
[0001] This utility model relates to the field of luggage, specifically to a multifunctional extension board and a box-type folding bed using the extension board. Background Technology
[0002] As people's travel needs diversify, the function of luggage is no longer limited to simple storage, but is gradually developing towards multi-functionality and modularity. Especially in scenarios such as outdoor travel and business trips, users often need to temporarily convert their luggage into a bed or work platform, while flexibly dividing the internal space to improve storage efficiency. However, the structure of traditional luggage is relatively simple, making it difficult to meet users' requirements for space expansion and functional partitioning.
[0003] In the existing technology, some bags attempt to achieve space division and functional expansion by adding partitions. However, existing partitions are usually only used for space division, with a relatively simple function. In addition, the connection method of the partitions is relatively simple, relying only on buckles or plug-in structures for fixation. They are prone to loosening or falling off under stress, affecting the user experience and need to be improved. Utility Model Content
[0004] The purpose of this utility model is to provide a multi-functional extension board that is firmly connected and can expand the usable area, as well as a box-type folding bed that uses the extension board, in order to address the above problems.
[0005] To achieve the above objectives, this utility model discloses a multifunctional extension plate, including a plate body, a claw on one side of the plate body, the claw including half claws spaced apart on the left and right, the half claws on the left and right surrounding each other, an insert plate on one side of the plate body, the insert plate including an extension plate connected to the plate body, and a positioning plate at the end of the extension plate.
[0006] The half-claw provides clamping and positioning for the extension board, facilitating quick engagement and disengagement. Using the claw, the board is installed inside the bag and can be used as a divider to separate the bag's interior into different functional areas. The L-shaped insert allows the extension board to be inserted into the bed board or extension panel, expanding the usable area of the bed board.
[0007] One side of the panel has a hanging plate, and the other side has a locking plate. When using two bags, after unfolding both bags, the insert plate can be inserted into the expansion hole of one bag, and the hanging plate can be inserted into the expansion hole of the other bag, thus bridging the two bags and further increasing the usable area and improving space utilization. The locking plate, when inserted into the slot of the positioning seat and with the locking claws, enhances the stability of the panel installation.
[0008] The plate is placed vertically, with the claws on the right side, the clamping plate on the left, the insert plate on the bottom, and the hanging plate on the top. This arrangement ensures a rational distribution of functional components, avoids interference, and facilitates installation and disassembly.
[0009] The insert plate is L-shaped, the extension plate extends forward, the positioning plate extends downward, and the half claw includes a bent part connected to the plate body. The other end of the bent part is provided with a straight part, and the shape of the half claw matches the shape of the positioning post.
[0010] The bottom of the board has a clearance groove, the sides have reinforcing ribs, and the board has expansion holes for inserting plates. A top plate presses against the upper side of the positioning plate above the expansion holes. The clearance groove avoids the internal structure of the luggage, improving compatibility, while the reinforcing ribs enhance the rigidity of the board, preventing deformation and increasing load-bearing capacity. Inserting the insert plate from one expansion plate into the expansion hole of another expansion plate can further expand the usable area of the bed board as needed, or it can be used as a headrest.
[0011] A box-type folding bed using this extension plate includes two half-shells. A hinge connecting the two half-shells is installed on one side of each half-shell. A positioning post for locking claws is provided on one inner side wall of each half-shell. A bed board is hinged to the half-shell, and another bed board can be hinged to the bed board. An extension plate is provided on the side of the half-shell. The board body, the extension plate, and the bed board are all provided with expansion holes for inserting plates. A top plate is provided on the expansion hole and presses against the upper side of the positioning plate. A support device is hinged to the bottom of the bed board. The box can be used as a bed after being unfolded.
[0012] The extension panel can be attached to a bag using clips to serve as a divider, or it can be removed and inserted into the extension holes of the extension panel or bed board to facilitate layout adjustments and increase the usable area of the bed board.
[0013] One side of the panel is equipped with a hanging plate, which is inserted into an expansion hole in the extension plate. When using two bags, after unfolding the two bags, the hanging plate can be inserted into the expansion hole of one bag and the other bag can be inserted into the expansion hole, thereby further increasing the usable area and improving space utilization.
[0014] One of the half-shells has a pull rod box for placing the pull rod, and the bottom of the panel has a clearance groove for avoiding the pull rod box, which allows the extension panel to fit snugly inside the box, improving space utilization and enhancing stability.
[0015] The semi-shell contains a support base for supporting the plate. The support base consists of two spaced-apart support plates, with the bottom of the plate inserted between the two support plates. This prevents the plate from swaying left and right when used as a partition, thus enhancing overall rigidity.
[0016] A positioning seat is fixedly installed inside the half-shell. The positioning post is located on the side of the half-shell where the hinge is installed, and the positioning seat is located on the opposite side of the positioning post. The positioning seat has a slot that extends vertically in a T-shape. A retaining plate is provided on one side of the plate, and the retaining plate is engaged in the slot. One end of the plate is engaged with the support post by a claw, and the other end is engaged with the slot by the retaining plate, which improves the stability of the expansion plate installation.
[0017] In summary, the beneficial effects of this utility model are as follows: the extension board can be installed in a bag using claws and plates to serve as a divider, thereby dividing the interior of the bag into different functional areas. Alternatively, insert plates can be inserted into the extension board or bed board to expand the usable area of the bed board. The bag can be used as a suitcase, unfolded as a bed, or used to build a temporary workbench. Attached Figure Description
